Question

Given the geometric sequence where a1 = −3 and the common ratio is 9, what is the domain for n?

Answer 1

All integers
All integers where n ≥ −1
All integers where n ≥ 1
All integers where n ≥ 0

Answer 2

The domain of ANY sequence is ALWAYS the set of natural numbers (aka the counting numbers). So the set: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, ...}

So that's why the answer is d. All integers where n ≥ 1
